Overview of product
The System Sensor SPSRK is a wall-mount outdoor speaker and speaker strobe that is designed to meet the requirements of various applications. It is a part of the SpectrAlert Advance line of outdoor speakers and speaker strobes that offers the broadest range of products in the industry. The SPSRK can be used both indoors and outdoors in wet or dry applications, and can operate reliably from -40ºF to 151ºF.
This device provides a broad frequency response range, low harmonic distortion, and high sound pressure level at all tap settings to provide accurate and intelligible broadcast of evacuation messages. It includes various features that increase application flexibility and simplify installation, such as field-selectable settings, automatic selection of 12- or 24-volt operation, and a universal mounting plate with an onboard shorting spring that ensures wiring continuity before devices are installed.
The SPSRK uses a plug-in design with a single captured screw to speed up installation and eliminate costly ground faults. It also ships with weatherproof plastic back boxes (metal back boxes available separately) that accommodate in-and-out wiring for daisy chaining devices. Knock-outs located on the back eliminate the need to drill holes for screw-in mounting. Plastic and metal weatherproof back boxes come with 3/4-inch top and bottom conduit entries and 3/4-inch knock-outs at the back.
Note that the System Sensor SPSRK is available for purchase by resellers only.
